Hi Kailash Thank you for looking at my issue. > I did some searching re UIDs and GIDs, and it appears that the > adduser.conf file can be used to manage this behavior. If I understand correctly, adduser.conf can be used to set the range of dynamically allocated uid/gid using FIRST_SYSTEM_UID and its friends. But I don't think that changing these defaults will help me. Also, I don't see that adduser.conf can be used to define which pkg gets which uid/gid within this range. If I understand correctly then this depends only on the sequence in which the packages are installed. > In addition if you look at the manpage of adduser the option "--uid" > will allow you to choose the user's ID.

So, I could try preempting them as James suggested, but I'm uneasy that that might cause the installs to abort or query. I need to test this. Or, I could allow the package install scripts to run, and then afterward fiddle with their values if necessary. I would also need to find all relevant files and chown them to the new values. If nothing breaks then that approach would be ok. But if things do/might break, then that approach is no good. Instead, I would need to control the install sequence of the packages. If so, what might be good approaches to achieve that? That is my question: 1) might it break? 2) If so, how best to avoid? > Please do refer to the policy manual re the allocation policy for > Debian. > http://www.debian.org/doc/debian-policy/ch-opersys.html#s9.2 Yes.
